Updating selenium from 2.44 to 2.45 seems to have fixed the problem.

Hi @cpsievert . I'm facing this very same issue. I was told in StackOverflow that one of the options I had was downgrading from my current firefox version (37.0.1) to 34.0.5. However, I'd like to give a try to updating selenium. I'd appreciate if you can guide me regarding how to do it (I'm using RSelenium, and it seems to be up to date (build is 2.44, though). Thanks

[cpsievert]

checkForServer() downloads selenium and places it in system.file("bin", package = "RSelenium") so something like this should do the trick:

unlink(system.file("bin", package = "RSelenium"), recursive = T)
checkForServer()

[PavoDive]

It worked like a charm! Thanks

Thanks @cpsievert

checkForServer(update = TRUE)

should also work I guess. Might be a good idea to clean up as you do however also 👍.

Hi, I got the same error when running in the ubuntu (Ubuntu 14.04.3 LTS, Mozilla Firefox 42.0,java version "1.8.0_66",R version 3.2.2 (2015-08-14) -- "Fire Safety", RSelenium 2.48.0"), however, if I run the same code in OS X EI Captian version 10.11.1, everything works fine(the Firefox, java, R's versions are the same). Meanwhile, the advices above still cannot solve my issue. Can you help me? Thank you.
